Comparative Physiology of Contrasting Genotypes of Loblolly Pine Under Dry Field

In this field study, effects of root and shoot genotypes on leaf physiology of loblolly pine (Pinus taeda L.) seedlings were evaluated and related to biomass production. A primary objective was to show whether physiological performance of different genotypes could be associated with productivity differences, when grown in a droughty environment. Productivity differences of these contrasting genotypes have been previously described and were related to biomass allocation among tree parts, especially to roots (Grissom and McKeand 1999). Differences in biomass allocation and production can be important, so understanding physiological origins and influences of root:shoot allocation within the tree may be informative. Such physiological properties may be particularly valuable if they can be used to detect genotypic differences in stemwood production, which may persist over time.
